Small Footprint ATMega328P Board

For my Word Clock project, for which I built a custom 8 x 8 LED Matrix with controller, I needed a much smaller footprint DIY-Duino (board for an ATMega328P microprocessor), one that would have all of the main functionality of my previous DIY-Duino boards (such as the Arduino Uno I2C Master board). As I'm not going to include I2C in the Word Clock, I can get rid of that without compromising the board and se ...

Getting Started With the ATMega328P

In the Internet of Things movement, people across the globe are connecting their stuff – TVs, pets, even houseplants - to the internet and transmitting all sorts of data. If you’re going to be a part of that movement, or want to dabble in creative prototyping on a budget, it’s important to get to know our little friend: The ATMega. The real benefit of using this microcontroller is that it’s only $4 US, wher ...

USBASP Bootloading a ATMega328p with a 8mhZ internal clock

What are we going to do is program an ATMega328P without an external crystal by using USBASP programmer and the Arduino IDE. Why would we want this? It uses less components and gets up closer to knowing how to program with something like WINAVR and because programming is fun an addicting. Not everything runs on Arduino, but it is a great place to start. I use an USBASP clone programmer from my local electro ...

Setup Arduino Software for Atmega328P with Internal Crystal on Breadboard

A breadboard Arduino will require an Atmega328P controller for these instructions. Note the “P” at the end of the name. You cannot use an Atmega328 because it has a slightly different device id number. It will require a different board configuration. Instructions for that are outside of this tutorial. Go to the Arduino tutorial website to get the board file to add to your sketchbook folder, Breadboard Tutor ...

Burn BootLoader into Atmega328P using Arduino Diecimila

I have an old Arduino Diecimila and some new Atmega328P-PU chips. Shouldn't have but I brounght some without bootloader to save some dollars. What next? search instructables to see if I can burn bootloader to ths chips. Unluckily not working. An error message "avrdude: stk500_getsync(): not in sync: resp=0x00 avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51" shown. There is a way to solder ...
